Benefits of technology

[0019] Advantageously, it has been discovered that fiber blends containing amorphous silica show improved char strength when formed into non-woven fabric, compared to non-woven fabric not containing amorphous silica. The strength t

[0047] The samples were prepared on a miniature card and needleloom. The fiber was first hand-opened and layered on the card feed apron. The carded sample was run back through the card a second time to assure intimate blending of fibers. The carded web, layered around the wind-up roll, was cut transversely and removed from the card. Then it was fed into the needlepunch line for needling. A second pass was performed to accomplish needling from the opposite side.

[0048] Standard tensile strength testers were modified to measure the char strength of the barrier fabric of the present invention. More specifically, the fabric stiffness test typically used with pocket coil material was modified to measure the amount of force, measured and reported in pounds, required to push a fabric sample through a hole with a plunger. To force the material to break, a template was fabricated so that the fabric could be sandwiched between the template and the existing test plate.

Abstract

A flame retardant or flame resistant (FR) fiber blend is provided that comprises amorphous silica fibers and at least one FR fiber. A flame retardant fabric, manufactured from a blend of fibers comprises amorphous silica fibers and at least one FR fiber. Barrier fabrics, manufactured from a blend of fibers, are provided comprising amorphous silica fibers and at least one FR fiber.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] None BACKGROUND OF THE INVENTION [0002] This invention relates to a flame resistant fiber blend useful in preparing fabrics having flame resistance and particularly non-woven flame resistant materials such as barrier fabrics. [0003] Flame retardant or flame-resistant materials (FR) are employed in many textile applications. For example, FR materials are useful as barrier layers between the exterior fabric and the inner stuffing of furniture, comforters, pillows, and mattresses. Such materials can be woven or non-woven, knitted, or laminated with other materials. [0004] The flame-resistance or flame-retardant properties of such FR materials are typically determined according to various standard methods, such as California TB117 and TB 133 for upholstery; NFPA701 for curtains and drapes; California Test Bulletin 129, dated October 1992, concerning flammability test procedures for mattresses in public buildings, and California Test Bulleti...
